Or maybe they’ll embellish the code to make it more efficient or applicable to the specific solution they are developing. But having the building-block idiom at their fingertips is a great starting point. Knowing and … [Read more...] about How to Process a File Line by Line in a Linux Bash Script

Next, tap the small microphone button located to the left of the space bar. (If you don’t see the microphone icon on your keyboard, make sure that Dictation is enabled on your device . To do so, launch Settings, then navigate to General > Keyboard and turn “Enable Dictation” on. And if your on-screen keyboard doesn’t appear , then you likely have an external Bluetooth keyboard connected.) After tapping the microphone button, the on-screen keyboard will be replaced with a moving waveform made out of lines that change based on how loudly you’re talking. As you speak, words will appear on the … [Read more...] about How to Type with Your Voice on iPhone and iPad
